Description
Technical Field
[0001] The utility model relates to the technical field of coating equipment, in particular to a new type of environmentally friendly coating and printing production line. Background Art
[0002] In the current printing and packaging industries, coating and printing production systems play a crucial role. Traditional coating and printing production lines are often designed for specific products and processes, which means they can usually only handle a limited variety of materials and coating requirements. Although this specificity ensures high efficiency and consistency in specific applications, it also brings obvious limitations, especially in the face of diverse customer needs, with obvious deficiencies in flexibility and adaptability.
[0003] Most coating systems on the market currently are of fixed configuration, that is, the number and layout of coating modules and drying modules are determined at the time of equipment factory shipment and cannot be adjusted according to actual production needs. This fixed structure results in the need to replace production lines or carry out cumbersome manual adjustments when dealing with papers of different thicknesses, materials, or coating requirements, not only increasing production costs but also reducing production efficiency. In addition, due to the lack of flexible modular design, the energy consumption and waste emissions of these systems are often relatively high, having a certain impact on the environment.
[0004] Therefore, the following problems exist in the prior art:
[0005] 1. Lack of flexibility: Unable to quickly adjust the production line configuration according to product characteristics and process requirements, restricting the applicable range of the equipment.
[0006] 2. Low production efficiency: The fixed production line configuration is difficult to meet diverse production needs, and frequent line changes and adjustments reduce production efficiency.
[0007] 3. Poor environmental protection performance: Non-modular design leads to energy waste and environmental pollution, not conforming to the development trend of green manufacturing.
[0008] In summary, developing a modular coating and printing production system that can be flexibly adjusted according to specific production needs has become the key to solving the above problems. The purpose of the utility model is to provide a new type of environmentally friendly coating and printing production line, by setting coating modules and drying modules that can be freely combined, to achieve flexible response to various coating processes, improve production efficiency while reducing resource consumption and environmental pollution, and meet the urgent market needs for high efficiency, high flexibility, and environmental friendliness. Summary of the Utility Model
[0009] In view of this, the purpose of the utility model is to provide a new type of environmentally friendly coating and printing production line, which has the characteristics of wide applicability and high production efficiency.
[0010] The technical solution adopted by the present utility model to solve its technical problems is as follows:
[0011] A new type of environmentally friendly coating and printing production line, including a frame. At the front end of the frame, there is an unwinding unit for inputting the substrate to be coated and printed. Inside the frame, a coating unit for processing the substrate is arranged in sequence from front to back. The coating unit includes several first coating units and a second coating unit. Above the first coating unit, there is a first heat treatment channel, and the second coating unit is connected to a second heat treatment channel; on the frame, there is also a winding unit for storing the processed substrate. The substrate can be coated through one or more of the first coating units, or the substrate can skip the first coating units.
[0012] On the frame, there is a feeding wheel group, and the feeding wheel group can transport the substrate output from the unwinding unit to the second coating unit.
[0013] The frame includes a first layer frame, a second layer frame, and a third layer frame. The feeding wheel group is arranged on the top of the second layer frame, the coating unit is arranged on the first layer frame, the first heat treatment channel is arranged on the second layer frame, and the second heat treatment channel is arranged on the third layer frame.
[0014] The coating unit further includes a third coating unit. The third coating unit can be connected to the second heat treatment channel, and the substrate can be transported from the second heat treatment channel to the third coating unit for flexographic printing operation.
[0015] On the frame, there is also a third heat treatment channel. The third coating unit connects the second heat treatment channel and the third heat treatment channel, and the substrate can enter the third heat treatment channel from the third coating unit.
[0016] Between the second heat treatment channel and the third heat treatment channel, there is a transition wheel group that can directly transport the substrate from the second heat treatment channel to the third heat treatment channel.
[0017] The first heat treatment channel, the second heat treatment channel, and the third heat treatment channel are all composed of a number of drying units spliced together before and after. The drying units are in a long strip shape, and there are conveying ports for inputting or outputting the substrate at the front and back respectively. The first heat treatment channel, the second heat treatment channel, and the third heat treatment channel are all arranged in an arched shape with the middle high and both ends low.
[0018] The first coating unit includes a coating wheel assembly for coating and processing the substrate; the first coating unit at the frontmost end is connected to a film releasing unit, and the film releasing unit is provided with a film combining wheel group, and the film combining wheel group can apply a film before the coating wheel assembly processes the substrate by coating.
[0019] The second coating unit includes a composite printing wheel assembly for performing coating and lamination processing on the substrate, and a doctor blade wheel assembly for performing doctor blade operation on the substrate.

[0020] In the first coating unit, the second coating unit, and the third coating unit, there are power wheel groups for providing conveying power to the substrate, and tension wheel groups for adjusting the tension of the substrate.
[0021] The beneficial effects of the present utility model are as follows:
[0022] 1. High flexibility and customization ability: When the substrate is fed from the uncoiling unit into the relatively independent first coating unit, the coating times can be adjusted according to the process requirements of the cardboard and the final forming effect, that is, the number of times entering the first coating unit can be adjusted. On the other hand, the first heat treatment channel is composed of several drying units, and there are conveying ports at both ends of each drying unit. The number of drying units entered can also be selected according to the process requirements of the cardboard and the final forming effect. That is to say, this production line can flexibly adjust the production line configuration according to different product characteristics and coating process requirements to achieve personalized production. Users can select the number of coating units and drying units to be enabled according to actual needs, and decide whether the substrate directly skips certain processes, such as directly conveying from the uncoiling unit to the second coating unit through the feeding wheel group, or directly conveying from the second heat treatment channel to the third heat treatment channel, greatly improving the flexibility and customization level of the production process.
[0023] 2. Significantly improve production efficiency: The processing steps of this production line are integrated on one frame, adopting a three-layer frame structure, which is compact in structure, reduces the conveying distance of the substrate, and shortens the production cycle. At the same time, through the optimized substrate transmission path, the ineffective waiting time of the material in the production line is reduced, realizing a continuous and efficient production process, and effectively improving the overall production efficiency.
[0024] 3. Energy conservation and environmental protection, reduce operating costs: On the one hand, select the number of coating units and drying units to be enabled according to different product characteristics and coating process requirements, and precisely control the operation of the equipment to avoid unnecessary energy waste. On the other hand, the heat treatment channel in this production line is designed with an arched structure, which is beneficial to maintaining an appropriate tension during the conveying process of the substrate by the wheel group, enabling the substrate to be fully unfolded, contributing to the uniform distribution and efficient utilization of heat, and reducing energy consumption.
[0025] 4. Simplified operation and maintenance: The modular design of the unwind unit, coating unit, drying unit, and rewind unit makes each part of the system easy to disassemble, install, and maintain, reducing the equipment failure rate and maintenance cost. At the same time, for operators, the modular structure means a simpler operation interface and more intuitive process control, reducing the training cost and improving the operation efficiency.

[0031] To make the technical problems solved by the present utility model, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the drawings and through specific embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all of them.
[0032] Referring to Figures 1-4 , the present invention provides a novel environmentally friendly coating and printing production line, including a frame 9. At the front end of the frame 9, there is an unwind unit 1 for inputting the substrate to be coated and printed. The frame 9 includes a first layer frame 91, a second layer frame 92, and a third layer frame 93. Inside the first layer frame 91, several coating units 2 for processing the substrate are arranged in sequence from front to back. The coating unit 2 includes several first coating units 20, a second coating unit 22, and a third coating unit 23. On the second layer frame 92, there is a first heat treatment channel 4 that can communicate with the first coating unit 20 and the second coating unit 22. On the third layer frame 93, there is a second heat treatment channel 5 that communicates with the second coating unit 22. On the frame 9, there is also a rewind unit 7 for storing the processed substrate, and the rewind unit 7 is connected to a third heat treatment channel 6;
[0033] Referring to Figure 1 ,Figure 2 , the processing steps of this production line are integrated onto a single frame 1, which adopts a three-layer structure. This structure is compact, reducing the conveying distance of the base material and shortening the production cycle. Meanwhile, through the optimized transmission path of the base material, the ineffective waiting time of materials in the production line is reduced, achieving a continuous and efficient production process and effectively improving the overall production efficiency.
[0034] Referring to Figure 2 , preferably, at least 4 first coating units 20 are provided. The second coating unit 22 is arranged at the rearmost end of the first layer rack 91, and the third coating unit 23 is arranged in front of the first coating unit 20 and in front of the second heat treatment channel 5.
[0035] Referring to Figure 2 , a roll feeding wheel set 24 is arranged at the top of the second layer rack 92. The roll feeding wheel set 24 is connected to the second coating unit 22, and the roll feeding wheel set 24 can directly convey the base material output from the uncoiling unit 1 to the second coating unit 22.
[0036] Referring to Figure 2 , a transition wheel set 25 is arranged between the second heat treatment channel 5 and the third heat treatment channel 6. The transition wheel set 25 can directly convey the base material output from the second heat treatment channel 5 to the third heat treatment channel 6.
[0037] Referring to Figure 2 , the first heat treatment channel 4, the second heat treatment channel 5, and the third heat treatment channel 6 are each composed of a number of drying units 40 spliced together front and back. The drying units 40 are in a long strip shape, and there are conveying ports 400 for inputting or outputting the base material at the front and back respectively. The first heat treatment channel 4, the second heat treatment channel 5, and the third heat treatment channel 6 are all arranged in an arched shape with the middle higher than both ends. Further, the arched structure is beneficial for maintaining an appropriate tension during the conveying process of the base material by the wheel set, enabling the base material to be fully unfolded, contributing to the uniform distribution and efficient utilization of heat, and reducing energy consumption.
[0038] Furthermore, when the base material is fed from the uncoiling unit 1 into the relatively independent first coating units 20, the coating times can be adjusted according to the process requirements of the cardboard and the final forming effect, that is, the number of first coating units 20 entered can be adjusted. On the other hand, the first heat treatment channel 4 is composed of a number of drying units 40, and there are conveying ports 400 at both ends of each drying unit 40. The number of drying units 4 entering can be selected according to the process requirements of the cardboard and the final forming effect.
[0039] Referring to Figure 2, the first coating unit 20 includes a coating wheel assembly 200 for coating the substrate. The first coating unit 20 at the frontmost end is connected to a film feeding unit 3, and a film combining wheel group 30 is provided on the film feeding unit 3. The film combining wheel group 30 can apply a film before the coating wheel assembly 200 coats the substrate. Further, the film feeding unit 3 can be selectively enabled according to the cardboard processing technology and forming requirements.
[0040] Refer to Figure 4 , the second coating unit 22 includes a composite printing wheel assembly 220 for coating and laminating the substrate and a glue scraping wheel assembly 221 for scraping glue on the substrate, and the third coating unit 23 includes a flexographic printing wheel assembly 230 for flexographic printing coating on the substrate.
[0041] Refer to Figures 2-5 , a power wheel group 81 for providing conveying power to the substrate and a tensioning wheel group 80 for adjusting the substrate tension are provided in each of the first coating unit 20, the second coating unit 22, and the third coating unit 23.
[0042] The modular design of the unwind unit 1, the coating unit 2, the drying unit 4, the winding unit 7, and the film feeding unit 3 makes each part of the system easy to disassemble, install, and maintain, reducing the failure rate and maintenance cost of the equipment. At the same time, for operators, the modular structure means a simpler operation interface and more intuitive process control, reducing the training cost and improving the operation efficiency.
[0043] The following are the specific processing steps for coating and printing the substrate:
[0044] S1: Place the substrate on the unwind unit 1 and start the unwind unit 1 to output the substrate to the coating unit 2 for coating operation;
[0045] S2: The substrate is output from the unwind unit 2 and passes through one or more first coating units 20, or the substrate is directly conveyed to the second coating unit 20 through the feeding unit 24 without passing through the first coating unit 20; Whenever the substrate passes through a first coating unit 20 for coating processing, the substrate needs to enter the first heat treatment channel 4 for drying operation;
[0046] S3: The substrate enters the second coating unit 22 for coating and laminating operation;
[0047] S4: The substrate is output from the second coating unit 22 to the second heat treatment channel 5 for drying operation;
[0048] Optional step S41: The substrate is output from the second heat treatment channel 5 to the third coating unit 23 for flexographic printing coating operation;
[0049] S50: The substrate enters the third heat treatment channel 6; further, when step S41 is not performed, the substrate can be conveyed from the second heat treatment channel 5 to the third heat treatment channel 6 through the transition pulley group 25;
[0050] S5: The substrate is output to the winding unit 7 for storage operation.
[0051] It should be noted that when the substrate enters the first heat treatment channel 4, the second heat treatment channel 5 or the third heat treatment channel 6, an appropriate number of drying units 40 can be selectively enabled according to the cardboard processing technology and forming requirements, rather than all the drying units 40 being in the enabled state when passing through the heat treatment channel.
[0052] This production line can flexibly adjust the production line configuration according to different product characteristics and coating process requirements to achieve personalized production. Users can select the number of coating units and drying units to be enabled according to actual needs, and decide whether the substrate directly skips certain processes. On the other hand, selecting the number of coating units and drying units to be enabled according to different product characteristics and coating process requirements also precisely controls the operation of the equipment, avoiding unnecessary energy waste.
